Product Description
This replaces the mounting ring of the polini air filter for vespa smallframe 19/19 carbs. The elliptical bell shape smooths and greatly increases the airflow. It will be required to rejet due to the much greater airflow. On our test bike we went from a 74 main jet to a 108. This design also has a serrated texture around the outside allowing the filter a much better grip.
No markup on this item, the price you see is what shapeways charges to make it.
I've enabled download of the STL file if you want to try and print it on a consumer grade printer, but the quality can't really compare.
